WALTER ROBERT SMITH, OF LOMPOC, CALIFORNIA.

VALVE.

Application filed March 24, 1921. Serial No. 455,076.

1 all whom it may concern:

Be it known that I, WALTER ROBERT SMITH, a citizen of the United States, and resident of Lompoc, county of Santa Barbara, and State of California, have invented a new and useful Valve, of which the fol lowing is a specification.

My invention while relating in general to valves has reference more particularly to an improved valve construction which is especially applicable to irrigating and the like systems of water distribution.

p The primary object of my invention is to produce a valve which while simple in construction and economical to produce is capable of carrying out its intended use with the greatest of efliciency and convenience both in installing and manner of operation.

-The invention possesses other features which will be apparent as the description proceeds with reference to the accompanying drawing in which Figure 1 is a perspective view of my improved valve prior to installation; Figure 2 is a vertical section of the valve as installed and showing a cap closure thereof closed, and Figure 3 is a vertical section of the valve prior to being' installed and showing the cap closure open.

Referring now to the drawing in detail; one of the salient features resides in the construction and cooperative relationship of the parts which enable the volume of discharge to be conveniently and efl'ectively controlled to which end I propose to construct the valve, of a pipe section (1) the lower end of which having a flange (2) which is adapted to be imbedded in concrete or the like (3) so that the pipe may be aligned with a pipe stand (4) such as is commonly used in irrigating systems for rows of fruit trees, vines and cultivated vegetation.

The upper or exposed end of the pipe (1) is preferably screw threaded as at (4:) so that the open end of the valve may receive a cap closure (5) which is capable of being threaded up and down on the pipe and with the cap closure provided with a plurality of openings (6) in its side which, when the cap is turned up will be exposed to produce discharge openings as best shown in Figure 3.

To increase or decrease the effective discharge area of the opening (6) the relative position of the cap closure to the opening in the pipe is regulated by turning the cap closure a predetermined number of times on the threads (4.)

When it is desirable to close the discharge the cap closure is turned down as far as it will go on the pipe (1) so that the top of the cap will overlie the opening in the pipe and with the openings (6) positioned below the upper end of the pipe. To effect a leak-proof cap, a suitable gasket (7) consisting preferably of an annular rubber fiber or the like rings arranged in an annular depression in the top of the cap closure, the gasket being arranged to bear against the perimeter of the open end of the pipe.

In order that the cap may be conveniently turned in opening and closing the valve, I prefer to arrange a radial slot in the top of the cap, which slot is made to receive a key or bar (8) the ends of which extending beyond the cap so as to increase the effective leverage necessary to turn the cap should it become stuck. I prefer to construct the pipesection (1) and the flange (2) of a metal casting and the cap closure (5) may also be of metal as well as the turning device (8).

From the above it will be seen that I have provided an extremely simple yet most effective and positive means for controlling the discharge area of irrigating pipes and particularly ameans whereby the discharge may be regulated which is highly desirable.

I claim:

In a valve of the class described, .a pipe section having a flange at one end adapted to be embedded in a cementbase with the pipe section in alinement with a Water distributing pipe, the opposite end of said pipe section being threaded, a cap closure for said threaded end including a plurality of openings in its sides, said cap closure adapted to be turned up and down on said threaded end for regulating the effective discharge area of the openings in the sidesthereof in respect to the opening in the top of the pipe section, a radial slot in the top of said cap closureand a key in said slot providing means for rotating the cap closure. substantially as and for the purpose described.

WALTER ROBERT SMITH.
